5. Most importantly and commonly used as an adjective to indicate that a person is under the influence of a controlled substance. It can be applied to any drug as long as it is not commonly supplied for recreational use. For something to be a drug, it has to be a chemical with an active effect on the body without being a nutrient, vitamin or mineral. So one can get high on fumes, medications, plant chemicals like THC, Fungal toxins found in mushrooms, synthetic chemicals like LSD, fermented waste materials, and animal biochemicals like adrenogland secretions. Please note that nicotine and alcohol use are not indicated by the word "high." For alcohol, the word used is "drunk" and for nicotine, the effect is so mild, it is almost never referred to at all.
6. Most of the time, "high" is used for being under the influence of Tetrahydrocannibinol, more commonly known as Marijuana or pot. For clarity, most speakers will indicate what drug is being used by adding the word "on" followed by the drugs name.
